To investigate the UV continuum slopes and ionizing properties of faint galaxies during the Epoch of Reionization.
Utilized JWST/NIRCam imaging in the Abell S1063 field to analyze 553 galaxies.
Estimated UV continuum slopes and applied empirical relations for escape fractions.
Analyzed constraints on the UV luminosity function and ionizing photon production.
Found a modest evolution in UV slopes with redshift.
Galaxies with M UV between -18 and -14 contributed approximately 60% of the ionizing photons.
Mean escape fraction peaks at around 20% for specific magnitudes and declines for fainter galaxies.
